Grammatically speaking, I think that [Formula does not compile.] is
better than [wrong formula].
However, I'm still very dubious about the improvement that this patch
confers. It seems to me that the only change to LyX's behaviour is
that exiting a just-edited inset will result in a [wrong formula]
preview as opposed to no preview at all. Loading an existing document
containing such an inset results in no previews being generated at
all, as now.
In conclusion, the existiing solution and your proposal convey appear
equivalent information, but yours introduces different (note, not
'better) behaviour for a 'just-edited' inset.
Forgive me, but I do not see why this is any improvement at all.
Kind regards,
